Ill is percentage illumination of the Moon


2025-Aug-01 UT 19:09-19:33 Ill=53% Montes_Caucasus

     Monte Caucasus: "shadow face" silhouette Clair-Obscur effect. 
     Clair-Obscur effects have no scientific importance just tricks 
     of the light that make us think we see something like 
     a letter of the alphabet or a shape or face. Clair-Obscur 
     effects are scientifically useless to observe. However, if 
     you want to be thrilled, or obtain an image to impress someone 
     then give them a go. This effect on the southern end of Montes 
     Caucuses looks like the side silhouette of a cartoon human face. 
     We are still slightly undertain about the precise colongitude 
     range, so if you do not see the face, try again later. If you 
     do observe, or image this, by all means send your observation 
     into ALPO or the BAA, but we probably won't publish, but will 
     nevertheless retain in our archives, just in case features 
     elsewhere in the image are of interest to future researchers.
     Note that we have some uncertainty in the colongitude range 
     - so if you don't see it, please tells us the date and UT so 
     we can make some improvements in the predictions.


2025-Aug-07 UT 21:54-22:22 Ill=97% Plato

     BAA Request: Two observers have reported colour on the rim 
     around this colongitude, once in 1938, and again in 2013. Please 
     take a look and report what you see, and where on the rim. 
     Please send any high resolution images, detailed sketches, or 
     visual descriptions to: a t c @ a b e r . a c. u k .


2025-Aug-10 UT 22:16-00:13 Ill=97% Tycho

     BAA Request: Tycho. We are trying to replicate, using 
     modern day images, a sketch in Plate X in BAA The Moon 
     from published: 1950 Jun Vol 1, No. 1. It is for a sketch made 
     by H.P. Wilkins from 1949 Jun 05. The original sketch was 
     made with an 12" telescope. Please send any images to: 
     a t c @ a b e r . a c. u k .


2025-Aug-11 UT 23:28-03:17 Ill=91% Cyrillus

     BAA Request: Cyrillus. There is a small white craterlet just 
     north of the three central peaks. We are interested to receive 
     high resolution images of this in order to find out at what 
     selenographic colongitude, in the lunar evening, that it loses 
     it's white spot appearence. Please use scopes largher than 6 
     inches in diameter. 
     Please email these to: a t c @ a b e r . a c . u k


2025-Aug-15 UT 23:30-03:55 Ill=51% Earthshine: Kappa Cygnids: ZHR=5 vel=21km/s

     These can only be observed using low-light level cameras running at 25 frames per sec,
     or faster, and capable of recording 9th or 10th magnitude stars in real time.
     Dates/UTs of observing runs, or detections of impacts, should be emailed to:
     ALPO - email: c u d n i k @ s b c g l o b a l . n e t
     BAA - email: a t c @ a b e r . a c . u k
     UAI - email: a m . 5 4 8 5 2 @ g m a i l . c o m


2025-Aug-17 UT 01:47-03:44 Ill=40% Plato

     BAA Request: Its around this Co-Longitude that some observers 
     have reported seeing an Ashen Light effect on the shadowed floor 
     of Plato, caused by scattered light off of an illuminated peak 
     on the rim. Please have a go either visually, or with long 
     exposure time lapse imagery to see if you can pick up the 
     development of this weak illumination effect on the floor. 
     Please send any sketches or images to: 
     a t c @ a b e r . a c. u k .


2025-Aug-17 UT 00:10-03:57 Ill=39% Earthshine: sporadic meteors
